Wolf's Milk

Also known as Groening's Slime, Wolf's Milk Slime Mold

Wolf's milk forms small, bubble-like cushions on damp decaying wood that change from bright pink or salmon to dull grayish-brown as they mature. When pricked early in development, these fruiting bodies squeeze out a thick, bright pink paste resembling pink toothpaste. Though frequently mistaken for a tiny puffball fungus, wolf's milk spends most of its life cycle as microscopic single-celled amoebae roaming rotting logs to engulf bacteria and spores.
